After 20+ years of rebuilding this drop box, these are the failure modes that drive most returning units. Every Midwest Industrial Sales rebuild addresses each one as part of the standard process — not just the failure that brought the unit in.
The most common reason an A40G drop box comes in for rebuild. Our heavy-duty differential package addresses the known OEM weak point that drives 20+ years of returning units.
Sensors fail in dusty haul-road environments well before downstream drivability complaints. Often shows up as fault codes the operator ignores until shifting degrades.
A known OEM weak point. High-cycle articulated-truck operation wears the shift fork assembly past spec. Every Midwest Industrial Sales rebuild installs the upgraded shift fork.
Dusty haul-road environments push moisture and grit past the OEM breather plate, degrading gear oil and accelerating bearing wear. We install an improved breather on every rebuild.
Every wear item in the drop box is replaced — not inspected and reinstalled. Bearings, seals, gaskets, and all wear bushings are 100% new on every rebuild.
Every 22568 / 22569 drop box that leaves our Gardner, Illinois facility has been fully torn down to housing castings, cleaned, inspected against factory specs, and reassembled with new wear parts. The heavy-duty differential package addresses the known OEM weak point. The shift fork is replaced with an upgraded assembly. All speed sensors, position sensors, and shift solenoids are new genuine OEM. Bearings, seals, and gaskets are 100% new. The breather plate is upgraded for haul-road contamination control. We do not just rebuild — we reinforce the OEM weak points first.
